Sometimes, you don't want those 45° corners in your nice, clean zones.
This adds an additional mode that can be selected, cycling through
free-angle, 45° angle and 90° angle constraints
Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
This also finishes the polygon with 45° lines when chosen as a create
option.

(cherry picked from commit fccce265aa959f5f234d32dcd29e01c1f25bd9a5)
If the client tool indicates it isn't happy for us to continue
(because, for instance, the user has cancelled the Zone Properties
dialog), then make sure we don't capture the mouse.

The zone creation in DRAWING_TOOL was a complex event loop whici
simultaneously managed the event handling, construction of the preview
polygon and the creation and commiting of the zone, all in the same
scope. This has been broken into several pieces:
* POLYGON_ITEM preview item, used to preview the polygon in progress
* POLYGON_GEOM_MANAGER is a class that collects points from user input
and used them to describe a polygon's geometry, including calculation
of 45-degree constrained leader lines
* ZONE_CREATE_HELPER is a class which deals with creating zones based on
geometry from a geometry manager and parameters from the DRAWING_TOOL
* The (much simpler) event loop in DRAWING_TOOL drives the
POLYGON_GEOM_MANAGER. With a minor refactor, this loop can be reused
in future for other polygonal tools if wanted.
The polygon preview now has a translucent fill which makes it easier to
visualise the zone.
This also adds the Close Zone Outline and Delete Last Corner actions as
part of the new event loop.
